CAR-DUMPING APPARATUS.

Specification of Letters Patent.

Application filed August 31,1906. S i 332.731-

To all whom it nmq concern.-

Be it known that LFREDERICK W. LOVVELL, i carried, the apron beingpivotally a citizen of the United States, residing at I to nuts carriedby said screw-rods C C and adjustable by the.

Cleveland, in the county of Cuyahoga and State of Ohio, have invented acertain new and useful Improvement in Apparatus, of which the followingclear, and exact description.

The object of the present invention is to so improve. car-dumping aparatus as to. the

better adapt it to the con itions obtaining in is a full,

its use.

The invention more particularly relates to a construction andarrangement whereby the 1 adjustable apron into which the car is dumpedmay be pulled up andout of the way in such manner as to clear therigging of vesi sels and to conform to the United States rcgu-' lationswith regard to projections over the dock-line and at the same timepermit the tower to be constructed and maintained close to the dock-linein order to obtain the obvious benefit which comes from the proximitybetween the two.

Referring to the accompanying drawings which illustrate an embodiment ofmy in vention, Figure 1 is a sideelevation of a hoistingtdwer with the(lumping pan or apron shown in full lines in a retracted or uprightposition, 0 the apron being also shown in dotted lines in the positionwhich it occupi s when being.

used. Fig. 2 is a top plan \'l('\\' of thc hoisting-tower. thedumping-apron being omitted. My tower is like other towers of this type,

5 provided. with a framework comprising cori ner-posts A A A" A, whichare -oiine -ted with the rest of the structure by -.i'oss-bi'ai-- ingand in such manner as to he as stable as possible. 40 the tower vtcndingfroni the posts A A at the front or apron side of the tower tothe rear posts A" A. These side girders are secured in any suitablemanner and carry between them transverse 5 girders B l l l Car-Dumping il l l l i i i l At the top of the l'raiiii-u'oih oi I provide sidegirders A" A, exi bonding-sheaves D B", the transverse girder l5extending from one side to the other across the. j

top of the tower. This girder B is set back some distance from the frontposts A A previously referred to, in order to allow a clear spacebetween these posts for a purpose hereinafter described.

Adjacent to the front, posts and in the rcs ent instance hanging fromsupporting-plates C at the top of said posts are the usual scrcwrods C Con which the dumping-apron D is trunnioned being therefore verticallyrotation of these rods.

The apron which I employ is of the usual type, being A-shaped-that is tosay, broad at its inner end and tapering toward a point atits outer endI) at which it carries a tele scoping funnel or chute nionly used in theart. The outer end of this apron is supported by means of ropes Dattached near its extreme outer and lower corner D". These ropes arereeved over sheaves D subsequently described, and in order to pro ventthe rope from catching on the sides of the A-shapcd apron when thelatter is in its Patented April 23, 1907.

D such as is com at the top of the tower, as will be lowered position Iprovide on the outer and upper end of the aprona more or less circular Vcasting I), over which the rope is led, so that it will be held awayfrom the sides of the apron when the latter is in the lowered position.

ill 'the top of thetowor are several short girders 3V, resting on thetwo transverse girders B B" previously described. These short girderscarry thereon the sheaves D over which are moved the ropes attached tothe outer end of the dumping-apron, the ropes being led down to ahoisting-drum E at the Aswill be seen from Fig. 2, these sheaves D are,owing to the structure just described, set back and in away from thefront edge of the tower, so that when the apron is raised the outer endD of the latter may )ass in between the forward posts A A and screw-rodsC U above de- (l'llJ((l. By having this structure in which the l'r\\'ard transverse girder B and the are set back so as to allow a clearspace between the screw-rods'C' (I by which the apron is pivotallysupported I am enabled to draw up the apron to such an extent that itdoes not project out so far as to interfere with the rigging of boatsand so as not to hang over the dock-line to any extent and yet obtainthis advantage without in any way lengthening the apron or increasingihe dimensions of the tower. It will be seen that the apron is, asheretofore; pivoted on a line with the front face of the tower and isnot of necessity altered as to its dimensions. It is a characteristicfeature of my invention that the her th-of the apron and distance'oi thefront ace of the tower from the dock-line may each remain the same asheretofore and yet the apron be withdrawn, so as to clear theobstructions and conform to the regulations, which it hithertoimpossible to do with, the same length of apron and the same proxirnitythe tower to thedook-line.

I have indicated in my drawings several conventional and ordinarystructures, such as the car-dumping platform and the sheaves and otherpieces of apparatus by which the apron and'tel scoping chute aremanipulated; but masmuc V v everyone 1n the art and l (10 not claim anynovelty therefor I have not encumberell the application by describingthem;

Having thus described my invention, .1
